3 Claims.

(Granted under the act of March 3, 1883, as

amended The invention described herein may be manufactured and used byor for the Government for governmental purposes, without the payment tome of any royalty thereon.

This invention relates to a gun carriage.

In wheeled gun carriages it is a common expedient to emplace thecarriage for firing by substituting a fixed support for the wheels. Thepurpose of the present invention is to provide a firing support that isassociated in a novel manner with the wheels and the brake mechanism forthe wheels.

To these and other ends, the invention consists in the construction,arrangement and combination of elements described hereinafter andpointed out in the claims forming a part of this specification.

A practical embodiment of the invention is illustrated in theaccompanying drawings,

wherein:

Fig. l is a view in side elevation of the improved gun carriage shown inthe travelling position.

Fig. 2 is a similar view of the carriage emplaced for firing.

Fig. 3 is a plan view of Fig. 1 with the gun removed.

Fig. 4 is a view in elevation of the inside of the right wheel.

Fig. 5 is a vertical sectional view through the wheel of Fig. 4., andshowing the axle in rear elevation.

Fig. 6 is a sectional view on the line 6-6 of Fig. 4.

Fig. 7 is a sectional view through the clamp.

Refering to the drawings by characters of reference, there is shown agun carriage consisting essentially of a trail A, axle B connectingbraces C and wheels D. In the present instance the axle includesdepending crank arms 5 for the purpose of lowering the spindles 6 onwhich the Wheels are mounted.

As shown in Fig. 5 the hub 7 of each wheel is formed internally with aflange 8 on which a brake drum 9 is secured by means of bolts 10. Aperipheral recess 11 in the flange is closed on one side by the brakedrum and in the groove thus provided is rotatably mounted a segment 12.The segment is formed with an offset 13 to clear the tire 14 on thewheel and on its outer edge is secured an arcuate shoe l5 overlying thetire l4 and spaced therefrom.

On the end of the segment opposite to the shoe there is secured abracket 16 threadedly mounting a clamp 17. A shoe 18 loosely mounted onthe clamp is adapted to engage the brake drum and has a lug 19 extendingalong the outer face of the drum. When the segment is in the lower orfiring position (Fig. 2) it is locked to the brake drum by means of theclamp.

April 30, 1928; 370 O. G. 757) The brake mechanism is of a conventionalin ternal expanding type and includes a backing plate 20 for the drumthat is secured to the crank 5 of the axle by means of bolts 21. A handlever 22 carrying a holding rod 23 engageable with a rack 24 is securedto the outer end of the usual actuating shaft 25.

Referring to Fig. 6 an arm 26 secured to the backing plate extends overthe brake drum and carries a casing 27 in which is mounted a springpressed latch 28. The latch is adapted to engage in an aperture 29 inthe segment 12 to hold it in the raised or travelling position.

In emplacing the carriage for firing the segments are unlatched andallowed to fall to the ground behind the wheels. The rear of the trailis then raised, the segments are locked to the brake drum by acting onthe clamps 17 and the brake drum is locked to the axle unit by acting onthe hand levers 22. The segments and trail are thus made to form a rigidunit and when the trail is lowered to the ground the carriage willrotate on the arcuate shoes 15. The parts will then be in the positionshown in Fig. 2. This operation is reversed when the segments are to berestored to the travelling position.

I claim:

1. In a gun carriage, an axle, a trail on the axle, wheels on the axle,a brake drum on each wheel, brake actuating mechanism carried by theaxle, a segment rotatably mounted on the hub of each axle and retainedby the brake drum, a shoe carried by each segment and overlying thewheel in spaced relation thereto, means on the axle for holding thesegment in inoperative position and means for clamping the segment tothe brake drum.

2. In a gun carriage, an axle, a trail on the axle, wheels on the axle,a brake drum on each wheel, brake actuating mechanism carried by theaxle, a segment rotatably mounted on the hub of each axle, a shoecarried by each segment and overlying the wheel in spaced relationthereto, means on the axle for holding the segment in inoperativeposition and means for clamping the segment to the brake drum.

3. In a gun carriage, an axle, wheels on the axle, a drum brakemechanism for each wheel, an emplacing member pivotally mounted on thehub of each wheel, and means for locking the emplacing member to thecorresponding brake mechanism.
